Figure 16. Compilation of data for the pseudoscalar coupling at the muon capture point g ? from experiment (A-E), BChPT (F-I), and lattice simulations (J-S). Extractions based on a dipole ansatz are colored red, while those using any variant of the z -expansion are colored blue. Some lattice calculations use an EFT ansatz colored green (pion pole term combined with Taylor ex- pansion). The error bands correspond to the result of our !2P (red) and our ! z 4+3 (blue) (cid:12)ts, with all errors added in quadrature. The lattice results in parentheses are outdated, since they are strongly a(cid:11)ected by the pion pole enhanced excited states treated in this article, cf. also
